OPHTHALMIC MOUNTING Filed Dec. 21, 1928 Patented May 17, 1932 UNITED STATES PATENT OFFICE EARLE J. RICHARD BEATTEY, OF EDGEWOOID, RHODE ISLAND, ASSIGNOR TO UNIVERSAL OPTICAL CORPORATION, OF PROVIDENCE, RHODE ISLAND, A CORPORATION OF RHODE ISLAND OPHTHALMIC MOUNTING Application filed December 21, 1928. Serial No. 327,504.

The invention relates broadly to ophthalmic mountings but more particularly to the bridges of eye-glasses and spectacles and the means for supporting the nose bearing pads.

The general object of the invention is to provide a bridge and means for supporting the nose bearing pads of a character to provide great flexibility of adjustment whereby mountings embodying the invention may be fitted upon persons having widely different physical characteristics.

It also is an object of the invention to provide means of novel and simple construction of a character such that the lenses may be adjusted readily both vertically and laterally with respect to the eyes of a person upon whom glasses are being fitted.

Other objects and advantages of the invention will be pointed out in the detailed description which follows or will be apparent from such description.

In order that the invention may be readily understood and the practical advantages of a mounting embodying the same fully appreciated reference should be had to the accompanying drawings wherein I have illustrated an embodiment of the invention in the form at present preferred by me.

In the drawings:

Fig. 1 is a view in perspective of a mounting embodying the invention;

Fig. 2 is a view in central vertical section taken on the line 22 of Fig. 3; and

Fig. 3 is a top plan View.

In the drawings I have shown a bridge comprising a central portion 1 which preferably is substantially flat and of rectangular shape in cross section. The opposite ends of the portion 1 are provided with rearwardly very nearly horizontally extending portions 2 which gradually are narrowed and merged into portions which are approximately of cylindrical shape in cross section, as indicated at 3. The portions 1, 2 and 3 need not of necessity be of the respective shapes in cross section as described, but when they are of the shapes described a very neat and artistic appearing mounting is produced. The extended cylindrical portions 3 are bent downwardly, as indicated at 4:, and

then forwardly, as indicated at 5, and again are bent downwardly, as indicated at 6, and then rearwardly, as indicated at 7. The portions 3, 5 and 7 may be described as arms and as being located generally in vertical planes at the opposite ends of the mounting. The extreme rear ends of the portions or arms 7 are bent and extended downwardly, as indicated at 8. These downwardly bent and extended portions 8 are secured to the outer sides of the nose bearing pads 9 which preferably consist of thin sheets of metal which may be of any shape which is suitable and which may be desired. The downwardly ex tended portions 8 may be secured to the portions 9 by welding or otherwise. The bends at 6 are secured to the inner sides of the straps 10 of known construction between the arms of which the lenses of glasses or spectacles are adapted to be secured in known manner. The straps 10 are secured to the bends 6 by welding or otherwise.

The rearwardly extending portions or arms 7 are each provided with outwardly extending bends 11. The presence of these bends not only increases the resilience of the arms 7 but also provides means whereby a greater range of adjustment of the nose bearing pads 9 may be efi'ected than would be the case if the said bends were not present. Furthermore, the presence of these bends permits adjustment of the pads 9 inwardly or outwardly so as to vary the distance be tween the same without altering the direction of the planes occupied by the said pads.

The presence of the arms 3, 5 and 7 located as described with respect to the nose bearing pads and the lenses constitutes means which provides great flexibility of adjustment. The ability to make the adjustments rendered possible by my invention enables the fitting of glasses upon persons having widely differing physical characteristics.

By widening the space between the arms 5 and 7 that is, by spreading the said arms, and then assuming that the nose bearing pads 9 will occupy the same positions upon the nose of a person being fitted with glasses, it will be apparent that the lenses may be elevated with respect to the eyes and with respect to the nose without any other change of relationships. In other words, such adjustments may be made without changing the plane occupied by the lenses. By varying the bends 11 either by increasing or decreasing the radii thereof the lenses may be adjusted transversely of the plane of the lenses so as to vary the distance thereof from the eyes. These bends 11, therefore, not only serve as means for increasing the spring or elastic character of the arms 7 but also as means for facilitating adjustments of the lenses with respect to the eyes.

By locating the arms3, 5 and 7 one above the other in a single general plane and by reason of the connection of the nose bearing pads 9 to the rear ends of the arms 7 I have provided means whereby the said pads may be adjusted angularly without in any way interfering with other parts of the struc ture; also the extent to which such angular adjustmentsmay be made has been increased.

It will be apparent that by my invention I have provided an ophthalmic mounting of novel construction having means whereby it may be adjusted to meet the conditions presented by the different physical characteristics presented by different persons who may be fitted with eyeglasses or spectacles.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. An ophthalmic mounting comprising a bridge the opposite end portions of which include a couple of arms located one above the other, a third arm connected at its front end to the front end of the lower of the said couple of arms, the three arms being located in approximately the same general vertical plane, and straps in contact with and secured to the connections between the front ends of the lowermost of the said couple of arms and the front end of the said third arm.

2. An ophthalmic mounting com rising a bridge having a central portion anc opposite end portions, the latter portions comprising two arms which are located rearwardly of the opposite ends of the said central portion, the arms constituting said opposite end portions being located one below the other, a third arm connected at its front end to the lower of the said two arms, and straps secured directly to the connections between the said third arm and the lower of the said two arms, the said straps connecting the opposite ends of the said bridge to the lenses of glasses.

3. An ophthalmic mounting comprising a bridge having a central portion and opposite end portions, each of the latter portions consisting of two arms which are located rearwardly of the opposite ends of the said central portion, the said arms being located one below the other, a third arm at each end of the structure, a connection betweenthe front;

end of said third arm and the front end of the lower of the said two arms, and nose bearing members mounted upon the rear ends of the said third arms, the said three arms being located in approximately the same vertical plane. Y

4. An ophthalmic mounting comprising a bridge having a central portion the opposite ends of which terminate in portions which extend rearwardly first downwardly and thenin a substantially horizontal direction, the latter portions being bent' downwardly'and then forwardly, the forwardly extending portions being located in a generally horizontal plane, the front ends of the said last mentioned portions being bent downwardly and extended rearwardly to form portions constituting arms which arms are provided with outwardly extending bends located intermediate the opposite ends-thereof and with downwardly extending; projections at their rear ends, nose bearing pads. mounted upon said extensions, and means for connecting the opposite ends. of the bridge to the lenses of a pair of glasses or spectacles.

In testimony that I claim the foregoing as my invention I have hereunto signed my name this 18th day of Dec., A. D. 1928.
